通知Notification

简单Notification

创建Builder

NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("My notification")
.setContentText("Hello World!");

添加Active

// 2. 创建点击回调动作
Intent resultIntent = new Intent(this, ResultActivity.class);
// Because clicking the notification opens a new ("special") activity, there's
// no need to create an artificial back stack.
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);

通知

// Builds the notification and issues it.
mNotifyMgr.notify(101, mBuilder.build());

后台调用

// Creates an Intent for the Activity
Intent resultIntent = new Intent(this, ResultActivity.class);
// Sets the Activity to start in a new, empty task
resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_CLEAR_TASK);
// Creates the PendingIntent
notifyIntent = PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);

移除Notification

调用后自动清除

builder.setAutoCancel(true);

指定的 notification ID调用了cancel()

指定的 notification ID调用了cancelAll()

接下来的几个样式就不说了，简单，先贴图再看代码
